Hello and welcome to Bleepingcomputer.
I read your discription in your complaint.
I see where you listed .30 Amps for the origional cooling fan.
You also listed the Radio Shack cooling fan as .16 Amps.
I am just curious as to what the Amps is listed on the power supply's label for the 12 volt rail amps output, as far as I can see it is listed as 18.8 Amps output on the 12 volt rail.
Contact Radio Shack and tell them the specs of your power supply and see if they have a fan with a rating closer to your current power supply's rating.
Also can you please tell me the catalog number of the fan you bought from RS?
Here is a link to Radio Shack's on-line store for cooling fans, the stores do not stock every piece of hardware available.http://www.radioshack.com/family/index.jsp...3071&s=null
